Adaface iOS (Swift) Online Test is the most accurate way to shortlist iOS Developers



Reason #1

Tests for on-the-job skills

iOS (Swift) online assessment test is designed and validated by industry experts to help tech recruiters and hiring managers assess iOS programming skills of the candidate. Top tech companies are using our iOS programming test to reduce candidate screening time by 85%.

The test ensures candidates have following traits:

  • Ability to write reusable iOS code
  • Ability to design and build advanced applications for the iOS platform
  • Proficiency in Swift/ Objective C with a good knowledge of its ecosystems
  • Experience of working with RESTful APIs to connect to back-end services
  • Top notch UI design skills
  • Experience integrating multiple data sources and databases
Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

These are just a small sample from our library of 10,000+ questions. The actual questions on this iOS Online Test will be non-googleable.

Solve
                        A startup company E-Motors is building driverless automated cars. The car contains a sensor that checks the road quality for the next N meters to decide the optimal speed at which the cars should move. We are given recorded data by the sensor in the form of an array, where each element of the array is the rating given to 1 meter of the road in sequence. 

The rating given by the sensor is from 1 to 100, where 100 represents the road with the best condition, and any rating above 60 is optimal. Find the longest stretch of road in meters that is categorized as optimal by the sensor.

The input is an array of "strings" which needs to be converted from string to integer/number inside the function.

    Reason #5

    1 click candidate invites

    Email invites: You can send candidates an email invite to the iOS Online Test from your dashboard by entering their email address.

    Public link: You can create a public link for each test that you can share with candidates.

    API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

    Reason #6

    Detailed scorecards & comparative results

    Reason #7

    Designed for elimination, not selection

    The most important thing while implementing the pre-employment iOS Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

    Reason #8

    High completion rate

    Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

    This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

    Reason #9

    Advanced Proctoring


    About iOS (Swift) Developer Job Roles

    iOS is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that presently powers many of the company's mobile devices, including the iPhone, and iPod Touch; it also powered the iPad prior to the introduction of iPadOS in 2019.

    An iOS developer builds, tests, and refines applications for mobile devices that use Apple's iOS operating system that are consistent with the goals and standards of their company or client. iOS developers most commonly program in Swift and Objective-C. Swift is a general-purpose compiled coding language released by Apple in 2014. It offers better type safety, security, and performance than Objective-C.

    Typical responsibilities of an iOS Developer include:

    • Designing and building mobile applications for Apple’s iOS platform
    • Ensuring quality and performance of application to specifications
    • Collaborating with a team to define, design, and ship new features
    • Continuously discover, evaluate, and implement new technologies to maximize development efficiency
    • Fixing application bugs before final release
    • Publishing application on App Store
    • Work on bug fixing and improving application performance

    The test is designed to screen candidates for roles like:

    • Junior iOS developer - Swift
    • Intermediate iOS developer - Swift
    • Senior iOS developer - Swift
    • Junior iOS developer - Objective C
    • Intermediate iOS developer - Objective C
    • Senior iOS developer - Objective C
    • Mobile developer
    • Swift developer
    • Objective C developer

    What roles can I use the iOS Online Test for?

    The hiring managers felt that through the technical questions that they asked during the panel interviews, they were able to tell which candidates had better scores, and differentiated with those who did not score as well. They are highly satisfied with the quality of candidates shortlisted with the Adaface screening.

    FAQs

    Can I combine multiple skills into one custom assessment?

    Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.

    Do you have any anti-cheating or proctoring features in place?

    We have the following anti-cheating features in place:

    • Non-googleable questions
    • IP proctoring
    • Web proctoring
    • Webcam proctoring
    • Plagiarism detection
    • Secure browser

    Read more about the proctoring features.

    How do I interpret test scores?

    The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

    What experience level can I use this test for?

    Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

    Does every candidate get the same questions?

    Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

    I'm a candidate. Can I try a practice test?

    No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

    What is the cost of using this test?

    You can check out our pricing plans.

    Can I get a free trial?

    Yes, you can sign up for free and preview this test.
